The integral of sin(mx) where m is a contant is always -1/m cos(mx)
Similarly the integral of cos(mx) is
1/m sin(mx)
Hope that helps
How the hell the he got -1/2cox 2x after integrating sin 2x dx?

A very quick reply, thanks!
Thanks fr the great video, I learned something new today :D
No, as the constant was never placed inside the bracket at the end. If it were I would want to call it 4C or A where A = 4C. Best to leave C outside though.
